Graphene quantum dots: In the crossroad of graphene, quantum dots and carbogenic nanoparticles

摘要

The scientific and technological importance of graphene quantum dots (GQDs) is directly related to theirudnanoscopic nature that endows remarkable photo-physical properties and colloidal stability in a variety ofudsolvents. GQDs combine characteristics arising from their graphitic structure, their carbogenic origin and theirudquantum nature. They are considered as the environmentally benign alternatives of heavy metal based quantumuddots, given that not only are they synthesized following green strategies, but they also exhibit minimal toxicity.udGQDs are systematically explored in printing, energy harvesting, bioimaging, catalysis, optoelectronics and sensingudapplications.
